In yet another embodiment, the sixth pole element can comprise a hinge joint, whereby the length of the sixth pole element is longer than the length of the first horizontal crossbar element. can do. In such embodiments, each individual portion of the sixth pole element can optionally be telescopically inserted into each other along with a hinge joint.

  Team sports or games played with skates (ice hockey, bandy), and especially ball games played on the ground, such as soccer, have goals that allow the ball to be put inside to win the game. I need. However, in many places the goal is not a permanent structure. This is because the same place is also used for other activities such as athletics, so that permanent goals prevent such activities, or the activities are seasonal (ice hockey, outdoor soccer, The goal must be resolvable. Also, one concern when storing goal parts is that such parts should not occupy a great deal of space in the containment area. As a result, there is a need for a foldable, portable, temporary goal structure that can be disassembled after the game ends or after the season is over.

Prior Art A foldable goal structure consisting of two vertical parts (poles) and horizontal parts (crossbars), which are mounted separately, is already known from GB patent application 2336322A. However, such goal structures are relatively far from current structures. This is because the common feature here is that the goal has two uprights and a crossbar, and all goals need to have it (some goals certainly lack a crossbar) However, this makes it difficult to calculate the goal score when a higher ball comes in).

  It is known from WO 2004/091737 A1 to provide the goal device with a flap for promoting advertising. However, nothing is said here about the pole structure itself.

GB Patent Application 2336322A WO2004 / 091737A1

  Hereinafter, the present invention will be disclosed with reference to the accompanying drawings.

1 shows an embodiment of a goal structure according to the invention in a folded position. Fig. 4 shows an assembly sequence of an embodiment of a goal structure according to the present invention. Fig. 4 shows an assembly sequence of an embodiment of a goal structure according to the present invention. Fig. 4 shows an assembly sequence of an embodiment of a goal structure according to the present invention. 5 shows the goal structure of the embodiment shown in FIGS. 1-4 in an upright position. 4 shows another form of the goal structure according to the present invention. Fig. 4 shows an embodiment of a hinge between a bar element and a pole element of a goal device according to the present invention.

  In its simplest embodiment, the foldable goal structure according to the invention comprises two pole elements 1, 2 together with a hollow crossbar element 3, with the upright pole elements 1, 2 in the crossbar element 3. Can be inserted. The upright pole elements 1, 2 are connected to the crossbar element 3 via hinge joint elements 4, 5 which can also be inserted into the hollow crossbar element 3. The hinge elements 4 and 5 correspond to positions where the axis of the upright pole element extends substantially perpendicularly to the axis of the crossbar element 3 from the position where the axis of the upright pole element substantially coincides with the axis of the crossbar element 3. The upright pole elements 1, 2 are connected so that they can be turned.

  All pole elements and pipe elements in the goal structure according to the invention are ensured their basic function (for example, placing the pole elements 1, 2 and the hinge joint elements 4, 5 into the crossbar element 3). As long as it is compact, it can be completely or partially hollow. The pipe element of the goal structure according to the present invention is preferably completely or partially hollow. This is especially because the weight can be reduced if the pipe element is hollow. However, the weight can also be reduced if all or some of the pole / pipe element parts in the structure are formed from a lightweight material such as plastic or aluminum. In this case, sufficient rigidity of the structure can be obtained by increasing the mass of all or part of the structural parts. Comparison of such a choice of structure with the choice of mass / hollowness of each part of the structure can be made by one skilled in the art.

  Further, all or a part of the pole element or the pipe element can be extended and contracted. This optionally makes the goal structure according to the invention as compact as possible and / or allows the size of the upright goal structure to be varied and / or stabilizes the upright structure according to the invention. Can do. In the case where the pipe / pole element of the goal structure according to the present invention is telescopic, a device capable of locking the pipe / pole element at their intended position relative to such pipe / pole element. It is preferable to provide it. Such possible locations can be fully deflated, partially deflated, or fully extended. Another possible locking device can be an internal expansion element that expands when the inner and outer pipe elements are rotated axially relative to each other. Such an expansion locking device also allows the length of the associated pipe / pole element to be locked in any expanded or retracted position. Another alternative locking device is to provide a hole in the outer or inner pipe element of the telescoping assembly and a corresponding peg that is pressed against the respective sliding element in the adjacent inner or outer pipe element. can do. Thereby, as the peg passes through the lock hole, it enters this lock hole, so that the associated pipe / pole elements are locked together. In such a locking device, the locking function is performed in stages. A third alternative locking feature may be to simply provide a mutual hole in the associated telescopic pipe / pole element so that when the holes are coincident, these holes are locked with a locking bolt. Can pass through.

  If all or some of the pipe elements in the goal structure according to the invention are telescopic or can be inserted into each other, in one alternative embodiment such pipe elements (eg crossbar element 3 and upright pole) Elements 1, 2 (see below) can be provided with internal traction elements such as elastic bodies and / or helical springs, whereby such telescopic elements are drawn together as soon as their axes are approximately coincident.

  In a simple embodiment of the goal device according to the invention initially described above, a peg or leg (not shown) can be provided at the end of the upright pole elements 1, 2 that are separated from the crossbar element 3 in the upright position, Thereby, for example, by pushing such a peg into the ground, an upright goal structure can be arranged in a safe manner. Alternatively, the upright pole itself can be pushed into the ground. However, only when the upright pole can withstand such a burden.

  In another embodiment, the goal structure according to the invention can be provided with hinge joint devices 6, 7 on the part of the upright pole element facing away from the crossbar element 3. Such hinge joint elements 6, 7 are further pipe elements 8 that can be moved so as to lie perpendicular to the upright pole elements 1, 2 and at an angle to the crossbar element 3. , 9 can be connected. In such an embodiment, the hinge joint elements 6, 7 can be provided with a hinge function, which allows the axis of the pipe elements 8, 9 to be parallel to the axis of the upright pole elements 1, 2 or upright poles. It can extend at least at an angle to the axis of the elements 1, 2. The angular interval covered by the hinge joint elements 10, 11 is preferably 0 ° to 90 °, most preferably 90 °. These hinge joint elements 6 and 7 are also provided with small areas 12 and 13, and the dimensions of the small areas are between the pivot function of the hinge joints 10 and 11 and the pivot function of the joints 6 and 7. It corresponds to the pipe diameter of the elements 1, 2 so that the pivoting of the pipe elements 8, 9 does not affect the arrangement of the pole elements 1, 2. In another embodiment, the hinge joints 6, 7 can always be at 90 °, and the hinges 10, 11 can be rotated from 0 ° to 90 °. In this embodiment, the pipe elements 8, 9 form the whole or part of the foundation area for the goal structure according to the invention. When the lengths of the pipe elements are individually equal to the length of the crossbar elements, the foundation area of the goal structure according to the invention in the upright state forms an equilateral triangle when the tips of the pipe elements 8, 9 meet. In such an embodiment, the hinge joint elements 6, 7 can be pivoted axially within their sockets of the pole elements, so that the pipe elements 8, 9 are folded out of the goal structure according to the invention. When in the state, it can pass through both sides of the crossbar element 3. Alternatively, the pipe elements 8 and 9 can be expanded and contracted so that their combined length corresponds to the length of the crossbar element 3 or is shorter than the length of the crossbar element 3. In this case, the pipe elements 8, 9 can pass through the same side of the crossbar element 3 when they are in the contracted state.

  In yet another alternative embodiment, the goal structure according to the invention comprises a further pipe element 14 (extending parallel to the crossbar element 3 and connected to the pipe elements 8, 9 via hinge joints 15, 16). Parallel elements). The hinge joints 15, 16 are arranged between 0 ° (the axes between the pipe elements 8, 9 and the parallel element 14 coincide with each other, FIG. 2) to 150 °, preferably 0 ° to 90 ° (FIGS. 3 to 4). Can function over any angular interval. Although the length of the parallel element 14 is arbitrary (the parallel element 14 can be expanded and contracted), in one embodiment, the length of the parallel element preferably corresponds to the length of the crossbar element 3.

  In yet another embodiment, the crossbar element 3 and the parallel element 14 can be joined so that they can be folded (see FIG. 6). Since the upright pole elements 1 and 2 and the pipe elements 8 and 9 are positioned in a state where their inner ends are in contact with each other when the goal structure according to the present invention is made compact, the crossbar element 3 and the parallel element By folding 14 and towards each other, the goal structure according to the present invention can be made even more compact. Where such an alternative is relevant, the crossbar element 3 and the parallel element 14 can be provided with internal pegs (not shown), whereby their halves that can be folded towards each other, In the assembled state, the halves can be supported in the joint area by being pressed onto their respective pegs, so that a strong joint is formed.

  As described above, the goal structure according to the present invention has been shown as a possible embodiment of the pipe element and the pole element forming the goal structure. A net material, cloth, plastic net or similar structure 17 (see FIG. 5) can be attached to or between the pipe and pole elements to form the preferred goal structure, Thus, the goal structure can be completed. Such a goal net can also be wound inside one or more pipe elements of the goal frame, or such a net material can be applied to the goal structure according to the invention after the goal frame is upright. It can also be fixed. In the embodiment depicted in FIGS. 1 to 5, such a net material 17 can be permanently fixed to the crossbar element 3 and the parallel element 14, and the net element has the aforementioned goal frame folding process. The side of the net material 17 can be loosened so that the goal frame can be folded as described above without disturbing.

  Another embodiment of the hinge 7 between the horizontal bar 9 and the vertical bar 2 of the goal device according to the invention is shown in FIG. In this embodiment, the hinge 7 includes an internal coil spring 18 that elastically connects the vertical bar 2 and the horizontal bar 9 to each other. This spring allows the goal device to be folded as described above, while the goal device can bend / bend elastically back and rebound, for example, when a pack or ball hits the crossbar 3 be able to. With this feature of the goal device according to the present invention, it is not necessary to fix the goal device very firmly, and the number of personnel required to fix the goal to the floor or the ground can be reduced.

  Small goals that displace from their proper position when applied are a major problem in the prior art. The feature of the elastically flexible hinge located between the horizontal pole 9 and the vertical pole 2 reduces or eliminates this problem.

  In FIG. 7, the elastic hinge is shown to include a coil spring 18. However, other elastic materials or devices can be recalled. As an example, a rubber hinge or even another type of elastic spring can be used in the hinge 7.
